Infineon Technologies IMZA65R048M1H | Demoboard EVAL_3KW_50V_PSU
Server and data center 3 kW 50 V PSU
Overview
| Topology | Power Factor Correction |
| Input voltage | 180-275 V |
| Output 1 | 50 V |
| IC revision | 1.0 |
Description
This evaluation board introduces a complete Infineon’s system solution for a 3 kW power supply unit (PSU) targeting the newly released OCP V3 rectifier specifications for servers and data centers.The PSU comprises a front-end AC-DC bridgeless totem pole converter followed by a back-end DC-DC isolated half-bridge LLC converter. The front-end totem pole converter provides power factor correction (PFC) and total harmonic distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage.The measured peak efficiency of the complete PSU at 230 VAC is 97.5%, not including the internal fan, and 97.4%, including the internal fan. The overall outer dimensions of the PSU are 73.5 mm x 520 mm x 40 mm, which yields a power density in the range of 32 W/inch³ (1.95 W/cm³).
Features
- Low capacitances
- Optimized switching behavior at higher currents
- Commutation robust fast body diode with low reverse recovery charge (Qrr)
- Superior gate oxide reliability
